From Business Insider, an article titled : The 10 Cities Most At Risk Of Being Hit By Natural Disasters . I cannot vouch for their selection methodology, but the results are interesting to consider. Only one U.S. city is on this list and that is Los Angeles.
Update: An eeire coincidence that on March 29, LA experiences a 5.1 magnitude earthquake and more than 100 aftershocks. Damaged to small number of residential structures have been documented. See this account from the LA Times.
On April 2, see this account from another LA periodical re the relative risk their metro area faces.
